U, SLOPE OPERATION
Slopes are a major factor related to loss of
control and tip-over accidents, which can
result in severe injury or death. Operation
on all slopes requires extra caution_ If you
cannot back up the slope or if you feel uneasy
on it, do not mow it.
Mow up and down slopes, not across.
Watch for holes, ruts, bumps, rocks, or
other hidden objects. Uneven terrain could
overturn the machine° Tall grass can hide
obstacles°
Choose a low ground speed so that you
will not have to stop or shift while on the
slope_
Do not mow on wet grass. Tires may lose
traction
Always keep the machine in gear when
going down slopes° Do not shift to neutral
and coast downhill°
Avoid starting, stopping, or turning on a
slope, tfthe tires lose traction, disengage
the blades and proceed slowly straight
down the slope.
Keep all movement on the slopes slow and
gradual. Do not make sudden changes
in speed or direction, which could cause
the machine to roll over,
. Use extra care while operating machine
with grass catchers or other attachments;
they can affect the stability ofthe machine°

sition.
ENGINE -
Move throttle control between half and full
speed (fast) position.
NOTE: Failure to move throttle control
between half and full speed (fast) posi-
tion, before stopping, may cause engine to
"backfire"°
Turn ignition key to "STOP" position and re-
move key.. Always remove key when leav-
ing tractor to prevent unauthorized use.
, Never use choke to stop engine.
IMPORTANT: Leaving the ignition switch in
any position other than "STOP" will cause
the battery to discharge and go dead,
NOTE: Undercertain conditionswhentractor
is standing idle with the engine running, hot
engine exhaust gases may cause "brown-
ing" of grass. To eliminate this possibility,
always stop engine when stopping tractor
on grass areas°
_CAUTION: Always stop tractor com-
pletely, as described above, before leaving
the operator's position.
TO USE THROTTLE CONTROL
Always operate engine at full speed (fast).
Operating engine at less than full speed
(fast) reduces engine's operating effi-
ciency.
Full speed (fast) offers the best mower
performance.
TO MOVE FORWARD AND BACKWARD
The direction and speed of movement is
controlled by the gearshift lever°
1. Start tractor with clutch!brake pedal
depressed and gearshift lever in neutral
(N) position.
2. Move gearshift lever to desired po-
sition.
3, Slowly release clutch/brake pedalto start
movemento
IMPORTANT: Bring tractor to a complete
stop before shifting or changing gears.

of your transaxle,
TO ADJUST MOWER CUTTING HEIGHT
The position of the attachment lift lever
determines the cutting height.
Grasp lift lever.
° Press plunger with thumb and move lever
to desired position.
The cutting height range is approximately
1-1/2to 4% The heights are measured from
the ground to the blade tip with the engine
not running. These heights are approximate
and may vary depending upon soil condi-
tions, height of grass and types of grass
being mowed.
13
. The average lawn should be cut to ap-
proximately 2-1/2 inches during the cool
season and to over 3 inches during hot
months. For healthier and better looking
lawns, mow often and after moderate
growth.
- For best cutting performance, grass over
6 inches in height should be mowed twice.
Make the first cut relatively high; the sec-
ond to desired height.
TO OPERATE MOWER
"Your tractor is equipped with an operator
presence sensing switch_ Any attempt
by the operator to leave the seat with the
engine running and the attachment clutch
engaged will shut off the engine, You must
remain fully and centrally positioned in the

"Your tractor is equipped with a Reverse
Operation System (ROS)_ Any attempt by
the operator to travel in the reverse direc-
tion with the attachment clutch engaged will
shut off the engine unless the ignition key is
placed in the ROS "ON" position°
_WARNING: Backing up with the at-
tachment clutch engaged while mowing is
strong ly discouraged. Turning the ROS "ON",
to allow reverse operation with the attach-
ment clutch engaged, should only be done
when the operator decides it is necessary to
reposition the machine with the attachment
engaged. Do not mow in reverse unless
absolutely necessary°
USING THE REVERSE OPERATION
SYSTEM -
1, Depress clutch/brake pedal atl the way
down and hold.
2. With engine running, turn ignition key
counterclockwise to ROS "ON" posi-
tion.
3. Look down and behind before and while
backing up.
4. Move gear shift lever to reverse (R)
position and slowly release clutch/brake
pedal to start movement.
5. When useofthe ROS is no longer needed,
turn the ignition key clockwise to engine
"ON" position.

_WARNING: Do not drive up or down
hills with slopes greater than 15 ° and do not
drive across any slope. Use the slope guide
at the back of this manual.
Choosetheslowestspeed before starting
up or down hills.
Avoid stopping or changing speed on
hills.
If stopping is absolutely necessary, push
clutch/brake pedal quickly to brake position
and engage parking brake.
Move gearshift lever to Ist gear Be sure
you have allowed room for tractor to roll
slightly as you restart movement.
. To restart movement, slowly release park-
ing brake and clutch/brake pedal.
Make all turns slowly.
TO TRANSPORT
o Raise attachment lift to highest position
with attachment lift control
When pushing or towing your tractor, be
sure gearshift lever is in neutral (N) posi-
tion.
= Do not push or tow tractor at more than
five (5) MPH°
NOTE: To protect hood from damage when
transporting your tractor on a truck or atrailer,
be sure hood is closed and secured to tractor°
Use an appropriate means of tying hood to
tractor (rope, cord, etc.).
14
TOWING CARTS AND OTHER ATTACH-
MENTS
Tow only the attachments that are recom-
mended by and comply with specifications
of the manufacturer of your tractor. Use
common sense when towing° Too heavy of
a load, while on a slope, is dangerous. Tires
can lose traction with the ground and cause
you to lose control of your tractor.
BEFORE STARTING 'THE ENGINE
CHECK ENGINE OIL LEVEL
The engine inyour tractor has been shipped,
from the factory, already filled with summer
weight oil.
1.. Check engine oil with tractor on level
ground.
2, Remove oil fill cap/dipstick and wipe
clean, reinsert the dipstick and screw cap
tight, wait for a few seconds, remove and
read oil level. If necessary, add oil until
"FULE' mark on dipstick is reached. Do
not overt_ill,
For cold weather operation you should
change oil for easier starting (See the oil
viscosity chart in the Maintenance section
of this manual).
To change engine oil, see the Mainte-
nance section in this manual.
ADD GASOLINE
Fill fuel tank to bottom of filler neck. Do
not overfill, Use fresh, clean, regular
unleaded gasoline with a minimum of
87 octane. (Use of leaded gasoline will
increase carbon and lead oxide deposits
and reduce valve life) oDo not mix oil with
gasoline_ Purchasefuel in quantitiesthat
can be used within 30 days to assure fuel
freshness.
_CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline near
an open flame.
IMPORTANT: When operating in temper-
atures below 32°F(00C), use fresh, clean
winter grade gasoline to help insure good
cold weather starting.
CAUTION: Alcohol blended fuels (called
gasohol or using ethanol or methanol) can
attract moisture which leads to separation
and formation of acids during storage. Acidic
gas can damage the fuel system of an engine
while in storage. To avoid engine problems,
the fuel system should be emptied before
storage of 30 days or longer, Drain the gas
tank, start the engine and let it run until the
fuel lines and carburetor are empty. Use fresh
fuel next season. See Storage Instructions
for additional information, Never use engine
or carburetor cleaner products in the fuel tank
or permanent damage may occur.
TO START ENGINE
When starting the engine for the first time or
if the engine has run out of fuel, it will take
extra cranking time to move fuel from the
tank to the engine
1. Sit on seat in operating position, depress
clutch/brake pedal and set parking
brake°
2o Place gear shift lever in neutral (N) posi-
tion.
3. Move attachment clutch to disengaged
position.
4. Move throttle control to choke position.
NOTE: Before starting, read the warm and
cold starting procedures below.
5. Insert key into ignition and turn key
clockwise to start position and release
key as soon as engine starts. Do not run
starter continuously for more than fifteen
seconds per minute, if the engine does
not start after several attempts, move
throttle control to fast position, wait a
few minutes and try again. If engine still
does not start, move the throttle control
back to the choke position and retry.
WARM WEATHER STARTING (50 ° F and
above)
6o When engine starts, move the throttle
control to the fast position.
- The attachments and ground drive can
now be used, If the engine does not
accept the load, restart the engine and
allow it to warm up for one minute using
the choke as described above.
15
COLD WEATHER STARTING ( 50 ° F and
below)
6. When engine starts, leave throttle control
in choke position until engine warms up
and begins to run roughly° Once rough
running begins, immediately move the
throttle control to the fast position° Engine
warm-up may take from several seconds
to several minutes (the colder the tem-
perature, the longer the warm-up)o
o The attachments can also be used during
the engine warm-up period.
NOTE: tf at a high altitude (above 3000
feet) or in cold temperatures (below 32 F)
the carburetor fuel mixture may need to be
adjusted for best engine performance (see
"TO ADJUST CAR BUR ETOR" inthe Service
and Adjustments section of this manual)_
MOWING TIPS
. Mower should be properly leveled for best
mowing performance See "TO LEVEL
MOWER HOUSING" in the Service and
Adjustments section of this manual
The left hand side of mower should be
used for trimming
, Drive so that clippings are discharged onto
the area that has already been cut Have
the cut areato the right of the tractor, This
will result in a more even distribution of
clippings and more uniform cutting
When mowing large areas, start by turning
to the right so that clippings will discharge
away from shrubs, fences, driveways,
etc° After one or two rounds, mow in the
opposite direction making left hand turns
until finished°
f
b,-
m ,,_.
00272
If grass is extremely tall, it should be
mowed twice to reduce load and possible
fire hazard from dried clippings. Make
first cut relatively high; the second to the
desired height.
Do not mow grass when it is wet. Wet
grass will plug mower and leave undesir-
able clumps, Allow grass to dry before
mowing.
Always operate engine at full throttle
when mowing to assure better mow-
ing performance and proper discharge
of material Regulate ground speed by
selecting a low enough gear to give the
mower cutting performance as well as the
quality of cut desired.
When operating attachments, select a
ground speed that will suit the terrain and
give best performance of the attachment
being used,
